LAMP-BURNER.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Application filed November 17, 1905. Serial No. 287,896.

To a/ZZ whom t may concern:

Be it known that I, GEORGE A. HALL, a citizen of the United States, residing at Buffalo, in the 'county of Erie and State of New York, lhave invented certain new and useful Improvements in Lamp-Burners, of which the following is a specification.

My invention relates to lamp-burners, and more particularly to that class of burners in which provision is made to lock the chimney thereto, so that in the careless handling of the lamp the chimney will not fall off.

The object of my invention is the production of a simple, durable, and inexpensive burner of this type which can be easily and quickly manipulated and in which two lockarms are used in conjunction with the usual spring retainer-arms that impinge against the exterior of the chimney at the base thereof and which lock-arms are manipulated by a simple, compact, and reliable operating device guided on the wick-tube and provided with means to maintain the device in any adjusted position.

My invention consists in the construction, arrangement, and combination of parts to be hereinafter described, and particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of my improved lamp-burner, showing the lower portion of a chimney locked thereto.

Fig. 2 is a central vertical section of the burner. Fig. 3 is a similar section taken at a right angle to Fig. 2. Fig. 4 is an inverted view of the burner. Fig. 5 is a longitudinal section through the operating device, taken on line .e z, Fig. 4. Fig. 6 is a detached perspective view of the operating device. Fig. 7 is a detached perspective view of the roughened cap of the screw-neck.

Referring now to the drawings in detail, like numerals of reference refer to like parts in the several figures.

The numeral 1 designates the body of the burner, comprising the gallery 2, screw-neck 3, having arms for securing it to the under side of the gallery, wick-tube 4, and a wickraising device 5, all of which may be of any common construction. The burner is also provided with the usual dome 6 and springretainers 7, adapted to bear against the outer face of the lamp-chimney, (designated 8 in Fie. 1.)

Tn connection with the above employ interior lock-arms 9, which extend through openings 10 in the gallery of the burner and are pivoted thereto, so that the upper ends of said lock-arms are swung outward when the lower ends are drawn inward. The upper ends of the lock-arms are curved outward, thence upward in the manner shown at 11, Figs. 1 and 2, so that the curved extremities thereof bear against the inner surface of the chimney at the enlarged or bulged portion 12 thereof. One or more of these lock-arms 'may be provided but I iind in practice that two arranged at diametrically opposite points render the burner very satisfactory.

Fitting into the open upper end of the screw-neck is a disk 13, provided with an elongated opening 14 to iit the wick-tube, and on either side of said opening the disk is crimped or roughened, as at 15. An operating-slide is held against the upper surface of the disk 13 by a flat spring 16, having its ends bearing against the under side of the gallery, said spring bearing against the upper face of an operating-slide 17 and having an elongated opening to fit the wick-tube. The operating-slide is provided with an elongated opening 18, through which the wick-tube is passed, said opening being longer than the width of the wick-tube to permit the slide to be moved back and forth on said tube. On either side of said slot the slide is crimped or roughened to correspond to the disk 13, the roughened surfaces of slide and disk serving to maintain the slide in any adjusted position. The ends of the slide terminate in depending lips 19, which form a convenient means of grasping the slide to operate the same, one of said lips being slotted at 20 to iit over the pintle 21 of the wick-raising device, which arrangement serves to guide the slide in addition to the guide provided by the wick-tube. Lateral extensions 22 are formed on said slide and provided with slots 23, arranged obliquely, or, in other words, at an angle to the direction of movement of the slide, and extending into or through said oblique slots are the lower extremities of the lockarms, which are drawn inward or forced outward on movement of the slide.

It is apparent from the foregoing that 1n operation the chimney is placed upon the gallery of the burner and within the retainers 7, while the upper ends of the lock-arms are drawn inward after which the operatingslide is manipulated to cause the upper ends of said arms to be forced outward in contact with the inner surface of the chimney, thus securely locking the latter to the burner.

IIO

Having thus described my invention, what I' claim is- 1. A lamp-burner provided with retainers adapted to impinge against the outer surface of a chimney, a lock-arm to engage the inner surface of the chimney and pivoted horizontally near its lower end to the burner7 and an operating device having a rectilinear movement and provided with a slot receiving the lower end of said `lock-arm and arranged at an angle to the direction of movement of said operating device.

2. A lamp-burner having the usual wicktube and provided with two radial swinging lock-arms adapted to engage the inner surface of the chimney, and an operating-slide guided for rectilinear movement on said wick-tube and having oblique slots receiving said lock-arms. i

3. A lamp-burner having the usual wicktube and provided with two 4radial swinging lock-arms adapted to engage the inner surface of the chimney, an operating-slide guided for rectilinear movement on said wick-tube and having oblique slots receiving said lock-arms, and meansto retain said operating-slide in any adjusted position.

4. A lamp-burner having the usual wicktube and provided with two radial swinging lock-arms adapted to engage the inner surface of the chimney, and an operating-slide having a longitudinal slot serving to guide the slide on the wick-tube and oblique slots receiving the said lock-arms, said slide having also a roughened surface to engage a fixed part of the burner, substantially as set forth.

5. A lamp-burner having the usual wicktube and provided with two radial swinging lock-arms adapted to engage the inner surface of the chimney, and an operating-slide guided for rectilinear movement on said wick-tube and having depending ends, and operative connection between said slide and the lock-arms.

6. A lamp-burner having the usual screwneck and wick-tube and provided with radially-movable llock-arms, a crimped cap for said screw-neck fitting around the wick-tube, and an operating-slide guided for movement on the Wick-tube and having a crimped portion coacting with said crimped cap to maintain said slide in the desired position, said slide having operative connection with the lock-arms to cause the latter to engage the inner surface of the chimney.

7. A lamp-burner having the usual screwneck and wick-tube and provided with radially-movable lock-arms, a crimped cap for said screw-neck fitting around the wick-tube, and an operating-slide guided for movement on the wick-tube and having a crimped portion coacting with said crimped cap to maintain said slide in the desired position, said slide having lateral extensions provided with oblique slots receiving said lock-arms.

8. A lamp-burner having` the usual gallery and screw-neck, and rovided with vertical lock-arms pivotally aflixed to the gallery and having their lower ends extending beneath said gallery, and an operating device guided for rectilinear movement between` the screwneck and the gallery and having oblique slots receiving the lower ends of said lock-arms.

ln testimony whereof I Ahave afiixed my signature in the presence of two subscribing witnesses.
